Universal Refrigerant Locking Cap Key

This universal locking cap key fits 410a and R22 refrigerant safety caps. It serves HVAC technicians and service professionals who need a single tool for multiple locking mechanisms. The three-bit design engages various cap interfaces across different HVAC systems. Compact and lightweight, it stores easily in a tool kit or on a keychain.

Suited for technicians handling mixed refrigerant

HVAC professionals who work with both 410a and R22 systems will find this multi-key efficient. It is compatible with Novent NG, NP, NPE Euro and NS Universal Locking Caps. Buyers who only service one refrigerant type or who need a powered valve core removal tool should look at a dedicated single-purpose instrument.

Verify cap compatibility before ordering

Confirm that the safety caps on site are Novent NG, NP, NPE Euro or NS Universal models. The tool is designed for tamper-resistant locking caps sold separately. Ensure the refrigerant in use is either 410a or R22. No other cap brands or refrigerant types are supported by this key.
